Question

A gas fills the right portion of a horizontal cylinder
whoseradius is 5.30 cm. The initialpressure of the gas is 1.01
105 Pa. A frictionless movable piston separates the
gasfrom the left portion of the cylinder, which is evacuated
andcontains an ideal spring, as the drawing shows. The piston
isinitially held in place by a pin. The spring is
initiallyunstrained, and the length of the gas-filled portion
is23.0 cm. When the pin is removed andthe gas is allowed to expand,
the length of the gas-filled chamberdoubles. The initial and final
temperatures are equal. Determinethe spring constant of the
spring.
